Title: Draw-leaf table with fixed main table top - has lower extensions and guide tracks raised up to correct level
Inventor: LERCH JOSEF
IPC: A47B1/05
Filed: 1973-12-21
Abstract: The table top is firmly connected to the table frame whilst the extension leaf or leaves which are housed beneath the table top can be drawn out beyond the edge of the table top into their front position where there is a free space between the edge of the table top and the facing edge of the extension leaf. In this position the extension leaf can be raised by hand to the same level as the table top and then pushed back to abut the latter where it is then fixed. The extension leaves run on guide tracks which pass through guides mounted on the table frame and table top and which can be vertically displaced in the latter. It is possible for the rear part of the guide track to be curved so that when it is extended it automatically rises to the correct table top height.

Title: Electric drive for camera - has automatic connection of drive motor to second battery for added torque
Inventor: BRAEUNING GERHARD
IPC: G03B19/18
Filed: 1974-04-01
Abstract: The camera drive motor is activated by a press contact which enables current to pass from the first battery to the motor via a diode. A special cam driven by the motor operates a first switch which maintains the motor supply for a set period, i.e. for one frame operation. A second cam on the main cam connects a second battery in series with the first for part of the sequence. This enables extra torque to be supplied for self processing cameras for the part of the exposure sequence when the film pack is dragged through the processing rollers. A simple electric motor can then be used. The system can also be fitted with a control switch to tear open newly loaded cassettes.

Title: Vehicle rear axle torsion suspension - with angled section metal cross member for torsion springing
Inventor: SCHWENK KURT ING GRAD
IPC: B60G3/14
Filed: 1974-05-28
Abstract: The rear wheels of the vehicle are supported on the ends of tubular trailing arms which can be bent into the required shape without loosing strength. The arms are mounted on the chassis on elastic bearings and have their upper ends joined by a cross member. For torsion springing with good bending resistance an angled profile is used for the cross member. The angle between the faces of the cross member is acute so that it can be taken into the tubular profile of the trailing arms with stress-free welds. Additional flanges between the cross member and the trailing arms strengthens the joints. The suspension has greater weld strength over a large range of torsion forces.

Title: Exhaust gas disposal - using detachable throwaway collecting vessels for exhaust gas storage for collection/disposal in central station
Inventor: JAHNS MAX
IPC: F01N3/00
Filed: 1974-08-24
Abstract: A system to prevent the pollution of the environment by internal combustion engines in motor vehicles and aircraft uses a receiver inside or outside the vehicle to store all exhaust gases. When full, it can be exchanged for an empty receiver, and the exhaust gases in the full receiver can be made innocuous by combustion or chemicals in a central plant. This is more certain way than individual exhaust gas purifiers which rely on proper maintenance for their function. It does not require any reduction in the lead content of the motor fuel.
